Here's an answer to the question about netmon's polling that you posted
December 10, 1998.
I've noticed something interesting that I can't explain...
On my Netview 5 system, I've got SNMP configured with one profile for the
whole network. I'm using the following values:
And that's about it. According to my Netview class, this should result in
the following behavior:
if no response, wait 2 seconds
if no response, wait 4 seconds
wait up to 8 seconds for response
if no response then device is down.
That is the way it used to work in NetView v4
I'm not sure what formula was used in v5.0
Here's the new scoop for v5.1:
Given: Timeout=2, Retry=5
Wait 2 seconds, ping
wait (2+1)=3 seconds, ping again
wait ((2+1)+1)=4, ping again
wait 2 seconds, ping last time
Total time (wasted) = 11 seconds
The scenario is:
Wait time out value, ping
Wait time out value plus 1, ping
Keep waiting and adding 1, ping
Last timeout will be original timeout
Total number of pings sent will be the "Retry value"
Retry of zero will be interpreted as "one ping only" (wasn't that a
line from Red October).
